Etiologic Risk Group (see link below): Risk Group lv 2 (moderate individual risk, low community risk) */Disease Information (sort of like the Intro to your Mini Research Write up): Streptococcus pneumoniae (S. pneumoniae) are lancet-shaped, gram-positive, facultative anaerobic bacteria with over 90 known serotypes. Most S. pneumoniae serotypes have been shown to cause disease, but only a minority of serotypes produce the majority of pneumococcal infections. Pneumococci are common inhabitants of the respiratory tract and may be isolated from the nasopharynx of 5-70% of adults, depending on the population and setting. Only 5-10% of adults without children are carriers. In schools and orphanages, 25-50% of students and residents may be carriers. On military installations, as many as 50-60% of service personnel may be carriers. The duration of carriage varies and is generally longer in children than adults. In addition, the relationship of carriage to the development of natural immunity is poorly understood.

Purification Method: DNA fragments were purified with the QIAEX II gel extraction kit (Qiagen, Hilden, Germany) according to the manufacturer’s recommendations. PCR-derived DNA fragments were cloned into the PCR II vector (Invitrogen). DNA sequences were determined for at least two clones. Cell walls were washed in H2O–1 M NaCl to remove the SDS and then purified by incubation with 200 μg of pronase/ml for 16 h, which was followed by the addition of 200 μg of trypsin/ml for 16 h. The mixture was then washed three times with 1% SDS, 8 M LiCl, and 100 mM EDTA and then was washed at least twice with H2O Image of protein (PyMol with features delineated and shown separately):
